Abstract

Abstract The push button switch according to the invention comprises a push button, a press member operated by the push button, a stationary contact member secured to a substrate and a movable contact member operated by the press member. One end of the movable contact member is shaped to engage the stationary contact member with a line contact whereby positive and low resistance contact is ensured. Further, a cushion member in the form of a resilient pad or spring is interposed between the press member and the push button for alleviating the shock created when the push button is depressed.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 211 words
A push button switch comprising a push button, said push button being of an inverted cup-shaped configuration, a press member housed within and operated by said push button, a cover plate having an aperture telescopically receiving said push button, a substrate beneath and spaced from said plate, a stationary contact member carried by said substrate, a cantilevered flexible contact member carried by said substrate and being disposed above said stationary contact member, said push button, press member and flexible contact member being in alignment whereby upon the depression of said push button said press member contacts and deflects said flexible contact member into contact with said stationary contact member, said flexible contact member having an end including means for providing straight line contact with said stationary contact member, spring means disposed between said push button and said substrate for normally biasing said push button in a direction away from said substrate, said inverted cup-shaped push button being defined by an end wall and a peripheral skirt, said spring means being in external telescopic relationship to said press member, a cushion member seated between said end wall and said press member, said substrate including a cover plate, and said spring means being disposed between said last-mentioned cover plate and said end wall.
